According to Kompas.com, the Samsung Galaxy Z Fold 8 features a new Flex Titanium display technology designed to strengthen the screen structure while reducing crease visibility, a claim recently tested by YouTuber Zack Nelson on his channel “JerryRigEverything.”
How Flex Titanium Changes Foldable Durability
Samsung built the Flex Titanium technology into the Galaxy Z Fold 8 to make the overall screen structure more resilient without losing flexibility. According to Samsung’s official statements cited by Kompas.com, this material engineering specifically targets the crease, making the fold line significantly more samar, or subtle, than in previous generations. This advancement arrives alongside strong market demand, following global pre-orders that surpassed 5 million units.
Outer Screen Performance Under Extreme Scratches
The device features a 5.5-inch outer display protected by Gorilla Glass Ceramic 3, which handles daily wear and tear differently than inner folding panels. During the durability test conducted by Zack Nelson on “JerryRigEverything,” the outer screen was subjected to a Mohs hardness pick test ranging from level 2 to level 9. According to the test results published by Kompas.com, visible scratches on the outer display began appearing at level 6, with deeper grooves forming at level 7.
Pro Tip: When evaluating foldable phones, pay close attention to the outer display’s Mohs hardness rating. While outer glass panels resist standard pocket debris like keys and coins well, inner folding screens require more careful handling due to their flexible polymer composition.
Main Screen Flexibility and Hardness Limits
Unlike the rigid outer glass, the 7.6-inch main screen of the Galaxy Z Fold 8 must bend continuously when the device opens and closes. Because of this mechanical requirement, the primary panel uses a much softer, more flexible material instead of traditional glass. According to the JerryRigEverything test documented by Kompas.com, scratches on this inner main screen appeared much earlier in the scale, showing marks at level 2 when exposed to everyday items like coins, keys, and a grappling hook.
Did You Know? The YouTuber Zack Nelson also subjected the Galaxy Z Fold 8 to extreme torture methods beyond scratching, including burning the inner panel with a lighter, coating the hinge in dust, and applying brute force to bend the device backward against its hinge.
Frequently Asked Questions
What is Flex Titanium on the Samsung Galaxy Z Fold 8?
According to Samsung, Flex Titanium is a new display technology engineered to make the folding screen structure stronger while keeping it flexible and reducing the visibility of the screen crease.
At what hardness level does the Galaxy Z Fold 8 outer screen scratch?
Based on the JerryRigEverything durability test reported by Kompas.com, the 5.5-inch outer screen protected by Gorilla Glass Ceramic 3 begins to show surface scratches at Mohs hardness level 6.
How does the inner main screen differ in durability from the outer display?
The 7.6-inch main inner screen uses a flexible material to allow folding, making it softer than the outer glass and prone to scratching at Mohs hardness level 2.
